The effectiveness of combined treatment with methylprednisolone and cyclophosphamide in oral paraquat poisoning. This chapter discusses herbicides other than the chlorophenoxy compounds, nitro- and chloro-phenols, arsenicals and dipyridyls, which are subjects of separate chapters. Many modern herbicides kill weeds selectively by impairing metabolic processes that are unique to plant life. Nonetheless, some pose a significant risk of poisoning if not handled appropriately, and may result in eye, skin and mucous membrane irritation. Herbicides mentioned in this chapter should be handled and applied only with proper personal protective equipment and careful attention to hygienic measures that minimize personal contact. Many formulations contain adjuvants (stabilizers, penetrants, surfactants) that may have significant irritating and toxic effects in addition to the primary herbicide. A number of premixed products may be combination formulations with additional active ingredients that are more toxic than the principal herbicide. Therefore, it is important to read the label to identify each active ingredient and its associated toxicities. Healthcare professionals should have a general understanding of the metabolism and health effects of these compounds after human exposures. Most of the watersoluble herbicides are primarily excreted, mainly in the urine, within 1-4 days. This chapter follows a slightly different format than the other chapters in this book. It has been studied extensively and is the subject of numerous publications in the medical literature. Propanil was previously described as having low toxicity; however, data from Sri Lanka have documented significant acute toxicity with the development of methemoglobinemia, including several fatalities. The listing cannot be considered inclusive, either of herbicide products or of effects. Glyphosate and related compounds have a specific mechanism of action inhibiting the enzyme responsible for synthesizing phenylalanine, tyrosine and tryptophan, which is an enzyme system that is not present in humans. Despite this, there have been a number of reports in the medical literature of acute glyphosaterelated poisoning. Most, if not all, of the symptoms may actually be related to the organic surfactant with which glyphosate is combined. Most moderate to severe symptomatic cases have been associated with intentional (suicidal) ingestion. More severe signs and symptoms may be seen in cases of intentional oral exposures. Cardiovascular, respiratory and renal systems may be affected; and signs and symptoms include tachypnea, dysrhythmias, hypotension, non-cardiogenic pulmonary edema, hypovolemic shock, oliguria and respiratory failure. Of the 601 cases, most were either asymptomatic (27%) or with minor symptoms (64%). Treat eye contamination by irrigating the exposed eye(s) with copious amounts of clean water or saline for at least 15 minutes. If irritation persists after irrigation, specialized medical treatment in a healthcare facility is indicated. In cases of severe poisoning resulting in acute renal failure, consider hemodialysis to correct acidosis and hyperkalemia. Methemoglobinemia has been reported in a mixed herbicide ingestion with the urea derivative metobromuron; however, it is likely that the latter was the cause of the methemoglobinemia. Benzonitriles Dichlobenil Casoron, Dyclomec, Barrier >4,460 Minimal toxic, irritant effects. Some reports of acute renal failure and respiratory failure have been reported with ingestion of large amounts. These herbicides do not uncouple oxidative phosphorylation or generate methemoglobin. Fluorodinitrotoluidine compounds Ethalfluralin Fluchloralin Trifluralin Imazapyr >10,000 1,550 >10,000 >5,000 Nicotinic idisopropylamine derivative Irritating to eyes and skin. Impaired consciousness, respiratory distress and severe vomiting occurs with large quantity (>100 mL) ingestion. Oxadiazolinone Oxadiazon Ronstar >3,500 Picolinic acid compound Picloram Tordon, Pinene 8,200 Irritating to skin, eyes, and respiratory tract. There is one report in the literature of metabolic acidosis following massive ingestion of prometryn. Desmetryn Metribuzin 1,390 1,100 Prometryn Triazines 5,235 Propazine >7,000 Simazine >5,000 Terbuthylazine Tertutryn 2,000 2,500 Some formulations of prometon are strongly irritating to eyes, skin and respiratory tract. Prometon Amitrole, aminotriazole 2,980 >10,000 Triazole Bromacil Uracils Lenacil Terbacil 5,200 >11,000 >5,000 Irritant to skin, eyes and respiratory tract. Ebuthiuron Flumeturon Isoproturon Urea derivatives Linuron 644 8,900 1,826 1,500 Methabenzthiazuron Metobromuron Metoxuron 5,000 2,000 3,200 Metobromuron has been associated with methemoglobinemia. Prior exposure must be determined from a recent history of occupational exposure or accidental or deliberate ingestion. Treat contamination of the eyes immediately by prolonged flushing with copious amounts of clean water. If dermal or ocular irritation persists, medical attention should be obtained without delay. Ingestions of these herbicides are likely to be followed by vomiting and diarrhea because of the irritant properties of most of the toxicants. Management depends on: (a) the best estimate of quantity originally ingested, (b) the time elapsed since ingestion and (c) the clinical status of the subject. If large amounts of herbicide have been ingested and the patient is seen within an hour of the ingestion, consider gastrointestinal decontamination as outlined in Chapter 3, General Principles. With the exception of treating methemoglobinemia associated with some of these herbicides, there are no specific antidotes for poisoning by most of these compounds. The exceptions to this rule are several insecticides (permethrin, lindane and malathion) that may be applied purposefully to human skin or hair to treat scabies and lice. Repellents are not insecticidal; rather they mask the human skin to detection by insects and arthropods (mosquitoes, gnats, ticks).

It discusses benzyl benzoate, borates, chlordimeform, chlorobenzilate, cyhexatin, fluorides, fipronil (an n-phenylpyrazone insecticide), haloaromatic substituted urea compounds, methoprene, neonicotinoids, propargite and sulfur. Absorbed benzyl benzoate is rapidly biotransformed to hippuric acid that is excreted in the urine. When given in large doses to laboratory animals, benzyl benzoate causes excitement, incoordination, paralysis of the limbs, convulsions, respiratory paralysis and death. If a potentially toxic amount has been swallowed and retained and the patient is seen soon after exposure, consider gastrointestinal decontamination. Toxicology When determining toxicity of boric acid from ingestion, it is important to distinguish between acute and chronic exposure. Chronic ingestion is more likely to cause 80 significant toxicity than acute exposure. A series of 784 patients has been described with no fatalities and minimal toxicity. Only 12% of these patients had symptoms of toxicity, mostly to the gastrointestinal tract. Consequently, cases of suicidal or accidental ingestion continue to be reported in the medical literature. Inhaled dust caused irritation of the respiratory tract among workers in a borax plant. Symptoms included nasal irritation, mucous membrane dryness, cough, shortness of breath and chest tightness. Nausea, persistent vomiting, abdominal pain and diarrhea reflect a toxic gastroenteritis. Cyanosis, weak pulse, hypotension and cold clammy skin indicate shock, which is sometimes the cause of death in borate poisoning. Studies of serum levels of boric acid and boron in non-poisoned individuals ranged from 0. Decontaminate the skin with soap and water as outlined in Chapter 3, General Principles. In acute poisonings, if a large amount has been ingested and the patient is seen within 1 hour of exposure, gastrointestinal decontamination may be considered as outlined in Chapter 3. It is important to keep in mind that vomiting and diarrhea are common, and severe poisoning may be associated with seizures. Monitor fluid balance and serum electrolytes (including acid base status) regularly. Test the urine for protein and cells to detect renal injury, and monitor serum concentration of borate if possible. If oliguria (less than 25-30 mL urine formed per hour) occurs, intravenous fluids must be slowed or stopped to avoid overloading the circulation. Such patients should usually be referred to a center capable of providing intensive care for critically ill patients. Consider hemodialysis in severe poisonings, if patient fails to respond to conventional therapy. Dialysis has been demonstrated to enhance the clearance of boric acid even in the presence of normal renal function. Exchange transfusion and peritoneal dialysis are rarely used today in acute poison management. Toxicology In a reported episode of occupational exposure to chlordimeform, several workers developed hematuria. Hemorrhagic cystitis, probably due to chloraniline biodegradation products, was the source of the blood in the urine. Symptoms reported by the affected workers included gross hematuria, dysuria, urinary frequency and urgency, penile discharge, abdominal and back pain, a generalized "hot" sensation, sleepiness, skin rash and desquamation, a sweet taste and anorexia. Decontaminate skin thoroughly with soap and water, as outlined in Chapter 3, General Principles. Decontaminate eyes by irrigating exposed eyes with copious amounts of clean water or saline for at least 15 minutes. If irritation persists after irrigation, send patient for specialized medical treatment in a healthcare facility. If chlordimeform has been ingested no more than an hour prior to treatment consider gastrointestinal decontamination as outlined in Chapter 3. Patients are at risk for fluid loss and subsequent electrolyte disturbances; young children are especially susceptible. Patients exposed should have serial urinalyses for protein and red cells to detect injury to the urinary tract. Based on observation of dosed animals, extreme absorbed doses may cause diarrhea, tachypnea, tremors, ataxia and muscle weakness. A case of toxic encephalopathy in a male following unprotected pesticide application in a field for 14 days at 10 hours per day has been reported. His symptoms included muscle pain, weakness, fever and mental status changes, progressing to a tonic-clonic seizure. If a large amount of chlorobenzilate was ingested within a few hours prior to treatment, consider gastrointestinal decontamination as outlined in Chapter 3. Toxicology Tricyclohexyl tin hydroxide is formulated as a 50% wettable powder for control of mites on ornamentals, hops, nut trees and some fruit trees. While information on the systemic toxicity of this specific tin compound is lacking, it should probably be assumed that cyhexatin can be absorbed to some extent across the skin, and that substantial absorbed doses would cause nervous system injury (see organotin compounds on page 154 in Chapter 16, Fungicides). Promptly decontaminate skin by washing with soap and water and decontaminate eyes by irrigating with clean water or saline for at least 15 minutes. Management should be as with other organotin compounds (see page 154 in Chapter 16, Fungicides). Sodium fluosilicate (sodium silico fluoride) has been used to control ectoparasites on livestock, as well as crawling insects in homes and work buildings. Commercial products containing sodium fluosilicate are no longer registered for use.

Nedocromil (Tilade) is an inhalational product that is used for maintenance therapy in the management of bronchial asthma. Such drugs should be avoided in patients with bronchospastic disorders because they may cause bronchoconstriction. It acts by stimulating primarily beta1-adrenergic receptors to produce an inotropic effect. Unlike dopamine, dobutamine does not cause the endogenous release of norepinephrine. Its use has been associated with the potential for the development of hepatic failure. It is the longestacting sympathomimetic bronchodilating agent with a duration of approximately 12 hours. It is available as an aerosol (Serevent) and as a powder for inhalation (Serevent Diskus). Because of its rather slow onset of action it is used only for maintenance and prophylaxis. Famotidine is an H 2-receptor antagonist that is used to reduce gastric acid secretion. It is believed to exert an antibacterial effect, thereby reducing the level of Propionibacterium acnes on the skin surface. The addition of clavulanate potassium to ticarcillin disodium extends the spectrum of antimicrobial coverage of this penicillin to include beta-lactamaseproducing organisms. It is a uterine stimulant that promotes uterine contractions, particularly during labor. At the time of ovulation, the concentration of each of these hormones reaches a peak, coinciding with the release of the ovum and the complete development of a mature endometrial wall. It is used in products such as Euthroid and Thyrolar as a thyroid hormone supplement. They may also cause some blockade of cholinergic, alphaI-adrenergic, and histamine receptors. It is capable of inhibiting the tubular secretion of penicillins and cephalosporins, thereby increasing the plasma levels of these drugs and prolonging their action in the body. Thus, 300 mg of phenoxymethyl penicillin is approximately equivalent to 480,000 units of activity. They are employed primarily in treating infections caused by beta-lactamase-producing staphylococci. Cyclosporine (Sandimmune) and tacrolimus (Prograf) are immunosuppressive agents employed in preventing rejection of transplanted organs. Because of its great ability to cause dependence, diacetylmorphine may not be legally prescribed in the United States. Because of its potential for producing a number of serious adverse effects, minoxidil is not a first-choice antihypertensive agent. Its ability to produce excess hair growth (hirsutism, hypertrichosis) has led to its topical use for the treatment of alopecia as the product Rogaine. It is also available in a transmucosal (Fentanyl Oralet, Actiq) and transdermal (Duragesic) dosage form. These symptoms are most evident shortly after consuming a lactose-containing food and may include bloating and diarrhea. Lactase enzyme is available as a liquid (Lactaid), caplets (Lactaid), capsules (Lactrase), or as chewable tablets (Dairy Ease). Cheilitis (cracked margins of the lips), conjunctivitis, and dry mouth occur in a large proportion of patients receiving this drug. Isotretinoin is classified in pregnancy category X and will, therefore, potentially cause fetal abnormalities. The drug is administered orally and must not be used in pregnant women because it carries a high risk of causing fetal deformities. Within seconds, it reaches the brain and produces central nervous system stimulation and euphoria. Uricosuric agents such as probenecid (Benemid) and sulfinpyrazone (Anturane) inhibit tubular reabsorption of urate and promote urate excretion. It is used in the management of acute myocardial infarction, acute ischemic stroke, and pulmonary embolism. Once injected into the circulation, alteplase binds to fibrin in a thrombus and converts the entrapped plasminogen to plasmin. It has been shown to inhibit the hepatic metabolism of drugs metabolized via the cytochrome P-450 pathway, thereby delaying metabolism and increasing serum levels. Cimetidine may affect the metabolism of drugs such as theophylline, some benzodiazepines, phenytoin, and warfarin. It is employed in the treatment of gout as well as in the management of patients receiving therapy for leukemia and other malignancies that increase uric acid formation. It is used in combination with calcium and parathyroid hormone in the treatment of hypoparathyroidism. Its use is associated with hepatic dysfunction and danger to the developing fetus. For example, the sympathetic branch utilizes norepinephrine, whereas the parasympathetic branch utilizes acetylcholine. It may cause a number of serious adverse effects, the most serious being pulmonary toxicity. Baseline chest x-rays and pulmonary function studies should be performed before therapy begins. It is employed in the treatment of severe pain and in maintenance treatment of narcotic addiction. The use of the drug seems to decrease the dissolution of hydroxyapatite crystals, the building blocks of bone tissue. The synthetic steroids prednisone and prednisolone exert similar actions on the body. This is believed to occur by the acetylation of platelet cyclooxygenase by aspirin. This in turn prevents the synthesis of thromboxane A 2, a prostaglandin that is a potent vasoconstrictor and an inducer of platelet aggregation. Spironolactone is an aldosterone antagonist that prevents the formation of a protein important for sodium transport in the distal tubule. Triamterene inhibits sodium reabsorption induced by aldosterone and inhibits basal sodium reabsorption. The drug is used for the short-term management of congestive heart failure in patients who have not responded adequately to digoxin, diuretics, or vasodilators. Higher levels do not seem to improve the therapeutic outcome and are likely to increase the chance of bleeding. Unlike lactose, which is hydrolyzed enzymatically to its monosaccharide components, oral doses of lactulose pass to the colon virtually unchanged.

Indeed, we wished to encourage health professionals to interface more closely with schools to ensure children with allergic disease receive optimal care. Copyright 2013 World Allergy Organization 4 Pawankar, Canonica, Holgate, Lockey and Blaiss 5) We considered that controlled trials should be conducted involving multiple interventions to examine the effect of ventilation, humidity and mite-reduction strategies on allergy development and control. We considered that the relevant government agencies, charities and other stakeholders should explore novel ways to educate young people about allergy and the prevention of anaphylaxis. Instead, we considered that food labels should clearly specify the amount of each allergen, and if it is contained within the products, we wish to discourage vague defensive warnings. Such products should warn those with a tendency to allergy that they may still get a marked reaction to such products. We recommend that further research into the relevance of IgG antibodies in food intolerance together with and the necessary controlled clinical trials should be conducted. Although my task was to direct our activity to issues relevant to allergy as occurs in the United Kingdom, nevertheless, it is remarkable how closely our recommendations from the House of Lords Report that I chaired resonate with those of the Allergy White Book. However, in general, patients with asthma are inadequately managed and asthma and rhinitis are both under-recognized1 for their impact on the health and decreased quality of life of those afflicted. In addition, studies to assess prevalence and care delivery show that there is a large variation among countries in the delivery of care to those suffering from asthma and allergy2. What is common among several countries, however, is that the majority of patients who seek medical advice for allergy and asthma are seen initially in primary care3 because there are inadequate numbers of trained allergists to meet the needs of so many patients4. It is, therefore, important that primary care physicians also assess the allergic triggers of these diseases. However, proper diagnosis and treatment for allergy and asthma are limited by the inadequate state of allergy knowledge within primary care. It represents international primary care perspectives in respiratory medicine trying to raise standards of care in individual countries and globally, through collaborative research, innovation and dissemination of best practice and education. This study may be used as a model of assessment by countries wishing to adopt a structured approach to care delivery or similar solutions for optimal patient care. These solutions, of course, need to be country-specific and will depend on national health care delivery systems. Some of these costs may as yet be poorly quantified, particularly the costs of presenteeism (when someone is present at work but with reduced productivity due to a disease or the treatment for that disease), as well as absenteeism. With the proper awareness of the scope of the problem, governments need to ensure that the training, skills and infrastructure exist with which to develop and provide effective and efficient care delivery. Introducing a structured allergy curriculum into undergraduate training may, of course, take several years to make a significant impact. However, given that allergy is so prevalent, allergy training in some form, even modular, should be considered an essential part of general professional training for all physicians. Guidelines in Allergy: Regularly produced and updated international and national allergic respiratory diseases guidelines will help to promote high quality care in primary care, Primary Care physicians need to be appropriately represented on these guideline committees to ensure that they are grounded in what is realistic and achievable. Recommendations for Competency in Allergy Training for Undergraduates Qualifying as Medical Practitioners: A World Allergy Organization Position Paper. While allergy does not enjoy the same level of public and governmental attention as other chronic diseases like cancer or cardiovascular diseases, it is certainly the most pervasive disorder globally. One major risk is that allergic diseases often are not perceived as serious chronic diseases and therefore are not diagnosed early enough and not treated consequently. In Europe, one in four children is allergic and it is documented that 87 million people suffer from allergies. This one airway concept needs to be better understood by the lay public since allergic rhinitis and asthma greatly impact the daily life of patients and their families, as well as their performance at school, work or social activities.

Karla Arruda, Fook Tim Chew Copyright 2013 World Allergy Organization 10 Pawankar, Canonica, Holgate, Lockey and Blaiss Section 3. Socio-economic Factors and Environmental Justice Rosalind J Wright, Michelle J Sternthal Section 3. Health economics, medical education and cost-effective health care in allergy Section 6. Therefore, it is imperative for this content to remain up-to-date as an authoritative global resource. Introduction the prevalence of allergic diseases worldwide is rising dramatically in both developed and developing countries. This increase is especially problematic in children, who are bearing the greatest burden of the rising trend which has occurred over the last two decades. In spite of this increase, even in the developed world, the care of patients with allergic diseases is fragmented and far from ideal. In light of the observations that adherence to treatment in Chronic Diseases is less then 50% and the cost of non adherence highly impacts the burden of chronic diseases worldwide, adherence needs to be a priority patientrelated outcome and an important step in patient education. Another important factor that comes into play are the gene-environment interactions. It has psychological effects, interferes with social interactions, and creates an economic burden not only for the affected subject, but for the family and for the society at large. There are unmet diagnostic, therapeutic, educational and financial needs to achieve better worldwide control of asthma. The burden of severe asthma is substantial with high perperson annual costs which can be largely attributed to medications, hospital admissions, and work loss. Atopic eczema is often the first manifestation of the atopic patient and early intervention may offer an opportunity to impede or stop the atopic march. Oral desensitization represents a promising approach to reduce the burden of disease caused by food allergy. Three major categories exist: a) spontaneous occurrence of wheals, associated with acute and chronic urticaria; b) wheals and angioedema elicited by specific stimuli, and in particular physical urticarias; and c) other urticarial disorders such as exercise-induced urticaria. Disparities in asthma morbidity and mortality, with an inverse relationship to social and economic status, are increasingly documented around the world. Skin tests should include relevant allergens and the use of standardized allergen extracts. There is a need for increased accessibility to allergy diagnosis and therapies and improved diagnostic methodologies that can substitute in vivo provocation tests for drug and food allergy. They have to make the initial clinical diagnosis, begin treatment and monitor the patient.

Hyperglycemia develops during pregnancy because the secretion of placental hormones causes insulin resistance antimicrobial on air filters studies about discount fucidin 10 gm online. Sensory neuropathy causes loss of sensation to antibiotic viruses order cheap fucidin pain and pressure; autonomic neuropathy causes an increase in skin dryness and the formation of skin fissures; motor neuropathy results in muscular atrophy infection vs disease order fucidin 10gm amex. Inadequate and compromised lower-extremity circulation interferes with the ability to get nutrients to the wound to promote healing and prevent the development of gangrene. Hyperglycemia impairs the ability of specialized leukocytes to destroy bacteria, thus lowering the resistance to infection. Peripheral vascular disease may prevent oxygen, nutrients, and antibiotics from reaching the injured tissue. Answer should include four of the following: steroids, proteins or peptides, polypeptides and glycoproteins, amines and amino acids, and fatty acid derivatives. The urine in the early stages of acute glomerulonephritis is characteristically cola-colored. Answer should include six of the following: lethargy, headache, muscle twitching, seizures, nausea, vomiting, and diarrhea. Answer should include six of the following: hypotension, air embolism, chest pain, dysrhythmias, pruritus, dialysis disequilibrium, painful muscle cramping, nausea, vomiting, and exsanguination. Urgency, burning, and pain on urination; frequency (voiding more than every 3 hours); nocturia; incontinence; suprapubic and pelvic pain; and sometimes hematuria and back pain. Answer should include four of the following: headache, fatigue, low back pain, engorged or painful breasts, abdominal fullness, mood swings, general irritability, fear of loss of control, binge eating, and crying spells. Answer should include six of the following: a history of thromboembolic disorders, migraine headaches with visual auras, cerebrovascular disease, breast cancer, pregnancy, liver tumors, post estrogen-dependent neoplasia, congenital hyperlipidemia, and abnormal vaginal bleeding. Depo-Provera, a long-acting progestin that is injected intramuscularly, effectively inhibits ovulation for 3 months. An emergency dose of estrogen or estrogen and progesterone, properly timed within 5 days, can prevent pregnancy by inhibiting or delaying ovulation. For in vitro fertilization, at an appropriate time, the egg is recovered by transvaginal ultrasound retrieval. Forty-eight hours after retrieval, the embryo is transferred to the uterine cavity by means of a transcervical catheter. The majority of nosocomial infections in the hospital are caused by instrumentation of the urinary tract or catheterization. Urethrovesical reflux refers to the backward flow of urine from the urethra into the bladder. Anticholinergics inhibit bladder contractions and are recommended for urge incontinence. Refer to chapter headings "Acute Pyelonephritis" and "Chronic Pyelonephritis" in the text. A biopsy excision of an inverted cone of tissue is performed when a Pap smear is "suspicious. Progesterone is the most important hormone for preparing the endometrium for the fertilized ovum. Ectopic pregnancy is the leading cause of pregnancyrelated death in the first trimester. A fertilized ovum implants in tissue other than the uterine area, usually the fallopian tube. Estrogen breaks down glycogen into lactic acid, which is responsible for producing a low vaginal pH. Refer to chapter heading "Pelvic Organ Prolapse: Cystocele, Rectocele, Enterocele" in the text. Refer to Figure 48-1 and chapter heading "Physical Assessment: Female Breast" in the text. Localized: vaginal discharge, lower abdominal pain, dyspareunia, and tenderness after menses. Look for a discharge from the nipples, puckering, dimpling, or scaling of the skin. Pay special attention to the area between the breast and the underarm, including the underarm area itself. Lie flat on your back, with your left arm over your head and a pillow or folded towel under your left shoulder. Answer should include four of the following: fever, perineal prostatic pain, dysuria, urinary tract symptoms (frequency, urgency, hesitancy, and nocturia). Answer should include five of the following: frequency of urination, nocturia, urgency and a sensation that the bladder has not emptied completely, hesitancy in starting urination, abdominal straining, a decrease in the volume and force of the urinary stream, recurring urinary tract infections, interruption of the urinary stream, and dribbling. Use three or four fingers of your right hand to feel your left breast firmly, carefully, and thoroughly. Beginning at the outer edge, press the flat part of your fingers in small circles, moving the circles slowly around the breast. Heparin is given prophylactically because there is a high incidence of deep vein thrombosis and pulmonary embolism after prostatectomy. Epididymitis is an infection of the epididymis that usually descends from an infected prostate or urinary tract. It passes upward through the urethra and ejaculatory duct and along the vans deferens to the epididymis. Refer to chapter heading "Benign Prostatic Hyperplasia (Enlarge Prostate)" in the text. Prolonged sitting increases intra-abdominal pressure and increases the possibility of bleeding. Teach the patient to tense the perineal muscles by pressing the buttocks together, holding the position for 15 to 20 seconds and then relaxing. Disorders arise from excesses or deficiencies of immunocompetent cells, alterations in cellular functioning, immunologic attack on self-antigens, and inappropriate or exaggerated responses to specific antigens. Passive acquired immunity is a temporary immunity transmitted from another source that has developed immunity through previous disease or immunization. Complement defends the body against bacterial infection, bridges natural and acquired immunity, and disposes of immune complexes and byproducts associated with inflammation. Once the immune system has been destroyed, stem cells can completely restore it with just a few cells. It is the time during which the viral burden set point is achieved and includes the acute symptoms and early infection phases. Refer to chapter heading "Immune Reconstitution Inflammatory Syndrome" in the text. It detects the allergen and indicates the quantity necessary to evoke an allergic reaction. Answer may include opportunistic infections, impaired breathing or respiratory failure, wasting syndrome, fluid and electrolyte imbalance, and adverse reaction to medications. Wasting syndrome and electrolyte imbalances and disturbances, especially dehydration 7.

Regarding condensed tannin compounds virus 101 cheapest fucidin, results in the literature about their effect on digestive enzyme activities are not consensual antibiotics to treat pneumonia purchase 10 gm fucidin overnight delivery. These authors observed that polymers showed a strong inhibitory activity against -amylase antibiotic resistance penicillin buy fucidin canada, while oligomers had a relatively weak effect. On the other hand, against -glucosidase activity, oligomers exerted a stronger protective effect than polymers. The most polymerized procyanidins (from pentamers to hexamers) were the most effective inhibitors of amylase activity rather than less polymerized structures (trimers). Therefore, phenolic compounds could in theory slow starch digestion by inhibition of these digestive enzymes and increase satiety by modulation of glucose "spiking" and depletion that occurs after carbohydrate-rich meals, which could make possible the use of these natural compounds as antidiabetic agents. Besides their influence on carbohydrate metabolism, phenolic compounds have also been reported to affect lipid metabolism being highly linked to weight gain, obesity, and cardiovascular protection. Several mechanisms have been reported by which they have these actions, including reduction of dietary lipid digestion and absorption from the gut. Once again, this inhibition occurs by interaction and inhibition of a digestive enzyme, lipase. Inhibitory effects of procyanidins increased according to the degree of polymerization from dimer to pentamer. On the other hand, pentamer or greater procyanidins showed maximal inhibitory effects on pancreatic lipase. These results suggested that with respect to in vitro pancreatic lipase inhibition, the degree of polymerization is an important factor. For instance, while epicatechin gallate, a common flavan-3-ol present in red wine, inhibits lipase significantly its counterpart epigallocatechin does not. Other authors support that the hypolipidemic effects of procyanidins are related to inhibition of other key enzymes in lipid biosynthesis pathways. Procyanidins also present the ability to interact with lipids reducing their availability. The micellar solubility of cholesterol in vitro is reduced significantly more by procyanidin dimers B2 and B5, trimer C1, and tetramer A2 than by catechin and epicatechin (Yasuda et al. The reversible binding of phenolic compounds to blood serum proteins, such as Wine Chapter 26 605 serum albumin, 1-acid glycoprotein, and lipoproteins has been reported (Diniz et al. Several authors report the interaction of human serum albumin and several red wine phenolic compounds, namely resveratrol (Lu et al. Similarly, Riedl and Hagerman (2001) found that the rate of radical scavenging by procyanidin dimer B1 was decreased in the presence of protein (model albumin and gelatin) because procyanidin and protein formed substantial amounts of perceptible complexes. Platelets are important elements of blood because they are active both in the initiation of thrombosis as well as within the development of atherosclerosis. It is also well known that patients with diabetes, hypertension, and patients who smoke have hyperactive blood platelets. Therefore, this activity of natural red wine phenolics to avoid platelet aggregation is also of great importance to prevent atherosclerosis. These authors studied a wide library of compounds and identified several structural features of phenolic compounds that diminished to a great extent this effect, such as saturation of the C-2, C-3 double bond, lack of the C-4 carbonyl, glycosylation at C-3, and a high number of hydroxyl substituents. Some works that studied the effect of two unrelated red wines, a Cabernet Sauvignon and a Muscadine wine, observed that Cabernet Sauvignon wine was effective in reducing the generation of A peptides, while polyphenols from the Muscadine wine attenuate A aggregation (Bitan et al. The authors identified anthocyanin polyphenolic components as those responsible for Cabernet Sauvignon. Regarding the Muscadine wine, they pointed out that its polyphenolics significantly interfere with A protein-to-protein interactions that are critical for the initial assembly of monomeric A peptides into increasingly large aggregated species. The same authors found that grape seed phenolic extracts enriched in proanthocyanidins are also capable of interfering with tau-mediated toxicity by interfering with the abnormal aggregation of tau (Santa-Maria et al. The results showed that the fixation to protein occurs in the peptide region where phosphorylations usually take place and the affinity has been shown to depend on the presence of some procyanidin structural elements (galloyl moiety and the degree of polymerization were shown to increase the affinity). The interaction of phenolic compounds with proteins can modulate the process of allergic sensitization and their direct effect on allergic symptoms. The ability of some phenolic compounds such as caffeic, ferulic, and gallic acid to form insoluble complexes with potentially allergenic proteins can render the protein hypoallergenic (Plundrich et al. This discovery confers no physiological relevance to some of the in vitro and animal studies performed with the original molecules and also to studies in Wine Chapter 26 607 which the concentration ranges are above the ranges detected in human plasma, urine, and fecal samples. Due to the almost absence of human studies concerning red wine bioavailability, this topic will include some data with the main red wine polyphenols as purified compounds or included in other food matrixes. All subjects consumed each beverage with different Mv3glc quantities: red wine 68 mg, dealcoholized red wine 58 mg, and red grape juice 117 mg Mv3glc was found in plasma and urine after ingestion of all the beverages studied and no metabolite or aglycone forms were observed in plasma or urine. Increases in plasma Mv3glc concentrations were not significantly different after the consumption of either red wine or dealcoholized red wine and were two times less than those measured after consumption of red grape juice. This difference may be caused by the about two times higher Mv3glc concentration present in red grape juice (Bub et al. Later, due to their low bioavailability, any significant contribution of anthocyanins to health-protecting properties of red wine or red grape juice after consumption by healthy volunteers was questioned (Frank et al. The intestinal absorption of anthocyanins of red grape juice seemed to be improved compared to red wine, suggesting a possible synergistic effect of the glucose content of the juice (Bitsch et al. The key difference compared to the other flavonoid glycosides, is that anthocyanins undergo rearrangements in response to pH and temperature (Brouillard and Delaporte, 1977). Actually, anthocyanins have been reported to have one of the lowest bioavailabilities of all of the dietary flavonoid subclasses (Manach et al. Upstream of gastrointestinal absorption, a variety of binding processes can take place, namely interaction with food proteins or with salivary proteins and digestive enzymes, as previously described (Matsui et al. Some studies have been conducted aiming at understanding the fast kinetics of plasma appearance of anthocyanins (Cao and Prior, 1999; Milbury et al. Moreover, a high proportion of pelargonidin-3-glucoside was found to be rapidly absorbed from rat stomach (Felgines et al. A different picture appears with radiolabeled anthocyanins and the detection of anthocyanin metabolites or catabolites. A current study using 13C-labeled anthocyanins carried out in humans by Czank et al. The accumulation of multiple phenolic metabolites might ultimately be responsible for the reported bioactivity of anthocyanins, with the gut microbiota apparently playing an important role in the biotransformation process. Long elimination half-lives may be the result of a combination of hepatic recycling, enterohepatic circulation, and prolonged colonic production and absorption. After anthocyanin-rich grape juice consumption the most abundant anthocyanins found in plasma and urine were malvidin and peonidin as native anthocyanins and as glucuronidated metabolites as well as 3,4-dihydroxybenzoic acid; minor anthocyanins (delphinidin, cyanidin, and petunidin) were only detected as native glycosides (Kuntz et al. All in all, these data suggest that anthocyanins would be as bioavailable as other flavonoid subclasses, such as flavan-3-ols and flavones, which have relative bioavailabilities between 2. Chemical reactions of phenolic compounds are particularly important in wine because they are responsible for the color and taste changes that occur during aging. Grape phenolic compounds, namely, anthocyanins, flavonols, hydroxycinnamic acids, and flavanols including catechins and proanthocyanidins, represent only approximately one half of the polyphenol content of a 2-year-old red wine polyphenol extract (Cheynier, 2005).

Initial non-specific symptoms usually precede the development of jaundice by 5-10 days antibiotic with least side effects purchase fucidin us. Darkening of the urine precede jaundice infection hemorrhoids 10gm fucidin mastercard, which peaks in 1-2 weeks and then begins to antimicrobial agents fucidin 10gm on line subside. Differential diagnosis Before jaundice appears, the symptoms are those of non-specific enteroviral diseases Note: Hepatitis mainly resolves spontaneously (95%) but rarely complicates into fulminant Hepatitis that is fatal. Elevated alkaline phosphatase, gamma glutamic acid and total and direct (conjugated) bilirubin levels are indicators of the degree of cholestasis, which may be a result of hepatocellular and bile duct damage. Prevention General measures: Sanitation and hygiene that includes hand washing, proper disposal of infectious materials. Mode of transmission Mainly through parenteral, sexual and vertical transmission 5% Clinical presentation the symptoms are non-specific, consisting only of slight fever (which may be absent) and mild gastrointestinal upset Visible jaundice is usually the first significant finding Dark urine and pale or clay-coloured stools Hepatomegaly is present Occasionally a symptom complex (caused by antigen-antibody complexes) of macular rash, urticarial lesion, and arthiritis antedates the appearance of icterus. Treatment Supportive o Low fat diet, oral fluids, o Give paracetamol (dose as above) if pain present Specific treatment o the use of interferon alfa in children has not yet established. Acute infection is often milder than Hepatitis A with moderately raised transaminases. Rabies Rabies is a zoonotic (transmitted from animals) viral neuroinvasive disease caused by a virus that belongs to genus lyssavirus in the family Rhabdoviridae. It is transmitted most commonly to human by a bite from an infected animal but occasionally by other forms of contact. Rabies is almost invariably fatal if post-exposure prophylaxis is not administered prior to the onset of severe symptoms. The incubation period of the disease depends on how far the virus must travel to reach the central nervous system, may take one week to six months. Once the infection reaches the central nervous system and symptoms begin to show, the infection is practically untreatable and usually fatal within days. Early-stage symptoms of rabies are malaise, headache and fever, later progressing to more serious ones, including acute pain, violent movements, uncontrolled excitement, depression and inability to swallow water. Finally, the patient may experience periods of mania and lethargy, followed by coma. In unvaccinated humans, rabies is almost always fatal after neurological symptoms have developed, but prompt post-exposure vaccination may prevent the virus from progressing. The same rules apply to persons vaccinated against rabies who have demonstrated neutralizing antibody titres of at least 0. Transmission the natural reservoir of the virus is unknown, the manner in which the virus first appears in a human at the start of an outbreak has not been determined. Researchers have hypothesized that the first patient becomes infected through contact with an infected animal. Through handling of infected chimpanzees, gorillas, and forest antelopes- both dead and alive Incubation period Incubation period is between 2 to 21 days. Signs and symptoms start with sudden onset of fever, intense weakness, muscle pain, Headache and Sore throat. These symptoms are followed by vomiting, diarrhea, rash, impaired kidney and liver functions. In some cases; rash, red eyes, hiccups, both internal and external bleeding can occur. Treatment There is no specific treatment, cure, or vaccine for Marburg Hemorrhagic fever. These include: o o o o Fluid and Electrolyte balancing Maintaining oxygen status Blood transfusion and clotting factors Treat for any complicating infections. It is related to Ebola virus and a parent type belongs to Viral Hemorrhagic fevers of Filoviridae family. Mode of transmission How the animal host first transmits Marburg virus to humans is unknown. However, humans who become ill with Marburg hemorrhagic fever virus may spread virus to other people. For example, persons who have handled infected monkeys and have come in direct contact with their fluids or cell cultures have become infected. Spread of the virus between humans has occurred in a setting of close contact, often in a hospital. Droplets of body fluids, or direct contact with persons, equipment, or other objects contaminated with infectious blood or tissues are all highly suspect as sources of disease. Transmission through infected semen can occur up to seven weeks after clinical recovery. Signs and symptoms are into two phases: Phase One: Sudden onset of fever, chills, headache and myalgia. Phase Two: Maculopapular rashes, Trunk rash, Nausea, Vomiting, Sore throat, Abdominal pain, Diarrhea, Jaundice, Pancreas inflammation, Severe weight loss Liver failure, Massive hemorrhage (all orifices), Multi-organ dysfunction, Delirium, Shock, and Death. These include: 353 P a g e o o o o Fluid and Electrolyte balancing Maintaining oxygen status Blood transfusion and clotting factors Treat for any complicating infections. Transmission to human is mainly through direct or indirect contact with blood or organs of infected animals. The virus can be transmitted to human through the handling of animal tissue during slaughtering or butchering, assisting with animal births, conducting veterinary procedures. Signs and symptoms are Influenza like illnesses: sudden onset of fevers, headache, myalgia, backache neck stiffness photophobia and vomiting. Most human cases are relatively mild small proportion develop a much more severe disease. Symptoms last from 4-7 days after which the immune response to infection becomes detectable with appearance of IgM and IgG. Most of human cases are relatively mild and of short duration so will not require any specific treatment. Though many cases of yellow fever are mild and self-limiting, the disease can also be a life threatening causing hemorrhagic fever and hepatitis. It is endemic in equatorial Africa and South America, with estimated 200,000 cases and 30,000 deaths annually. Once infected, mosquitoes remain so for life Treatment, prevention and control No specific anti-viral treatment, supportive therapies are recommended. Prevention and Control involve mosquito control and provision of yellow fever vaccine. Table 2: the schedule for immunization for children is as follow: Age Birth Vaccine 1. Onset of kala-azar is shown by low grade fever, splenomegaly, enlarged liver and lymphadenopathy.

Telemedicine has been piloted in some localities virus finder purchase fucidin 10 gm, and evaluation of its outcomes should be undertaken antibiotics meaning 10 gm fucidin visa. It is essential that the financial resources for outpatient providers to treatment for giardia dogs buy genuine fucidin on line fulfill this role be adequately available. Some local officials were concerned about outpatient competency restoration becoming an unfunded mandate that drains from already limited resources. The missing element of the psychiatric inpatient care continuum is a system of state-funded, but locally operated psychiatric hospitals that serve as regional "hub" facilities. Their design and intent would be to supplement and complete, not supplant, the existing short-term, acute stabilization system that has many well-intended and effective outcomes, but is impaired by the inability to place individuals who require longer term treatment so that the system may continue to serve those who would benefit from the short-term treatment for which it is designed, funded, and regulated. Additionally, they would provide longer term psychiatric treatment as needed to persons whose severity of illness requires a 45-day course of treatment to remediate the danger that the person presents to himself/herself or others as a direct result of the psychiatric disorder. To demonstrate local commitment, communities could be required to provide the funds to construct these facilities. Improve Access to Timely and High-Quality Outpatient Care for Youth Some adolescents who require hospitalization for behavioral health disorders experience relatively sudden onset of a precipitous decline in functioning. It is far more common, though, that the critical event that led to inpatient care was the cresting of a lengthy history of chronic behavioral and emotional distress that has already exacted a heavy toll in diminished quality of life and negative self-image. Families are beset by exasperation, frustrations in seeking help, and, quite often, selfreproach. However, the opportunities to provide families with effective treatments before these problems escalate are usually missed. Access to behavioral health services in both the rural and urban portions of our region for youth remains poor. Wait lists just for intake evaluations are typically on the order of weeks to months. However, resources for behavioral health therapies are scant, a problem that is exacerbated in our rural and frontier areas that send need to hospitalize adolescents when crises emerge. Coupled with the shortage of child and adolescent psychiatrists in Texas and elsewhere in the U. Indeed, in Bexar County a behavioral health/primary pediatrics collaborative program was implemented in 9 pediatric care settings that evaluated and treated over 10,000 youngsters in four years, only a small minority of whom would have received services otherwise. We also encourage development and evaluation of care models to improve access and quality. It may take some time to establish the impact of better outpatient services on hospital admissions for youth, but there is no doubt at all that they would immediately affect quality of care for children discharged from inpatient care who often cannot be seen in a timely fashion for follow-up services. We return to the topic of follow-up care in the next section on improved post-discharge quality of life. Education and Behavioral Health School based mental health programs can make a significant impact in improved access for youth. The Meadows Foundation in Dallas has long supported nationally recognized programs of this this type. When they can be implemented alongside school health clinics with prescribers who have access to specialist consultation via telepsychiatry then appropriate pharmacotherapy may be more widely available as well. However, one limiting factor has been engagement with families during school hours, and parents increasingly have less flexible work schedules. Some early evening hours in sites where this proves important would benefit from support. We urge collaboration with state and local educational authorities to improve the availability and programming for such services. Moreover, families should not have to relinquish parental rights in order for their children to access necessary treatment. The longterm effects of child abuse/neglect often require extended treatment before a child is ready for adoption. Child Abuse Affects Future Psychiatric Services Needs Child Abuse/Neglect as factors in mental illness. An extensive body of evidence now shows that childhood abuse and neglect are among the major factors in both childhood and adult mental illness. It is important to note, however, they are not the only causes, many cases of serious mental illness, including depression and anxiety, occur in loving families where there has been no abuse or neglect. Nonetheless, studies strongly suggest that preventing or intervening with early life adverse events could prevent or lessen the impact of mental illness. A meta-analysis combining 37 studies that involved over 3 million individuals looked at the impact of sexual abuse as a risk factor for psychiatric disorder (75). Of growing concern is that childhood abuse and neglect have long lasting effects on the brain development (77). In essence, persons with a history of abuse tend to have an excessive stress response by releasing abnormal amounts of cortisol and adrenaline in response to life events. Abuse persons may experience alterations to their immune systems, producing an inflammatory response that may be damaging to variety of organs and be related to chronic disease (77). In children, severity of early life stressors are associated with smaller brain volumes in areas that are critical for memory and advanced thinking. Each "case" may represent many children in a family, thus there was a total of 289,796 victims of child abuse/neglect in Texas in fiscal 2017 (38. The number of children taken into state custody was 48,889, while 29,803 children were in state custody as of August 31, 2017, with only 7,236 eligible for adoption. There is a high rate of teen pregnancy among youth in foster care and young people who have aged out of foster care (81, Table 14b Pregnancies of Women Age 13-17, Table 14b Pregnancies of Women Age 13-17) Girls age 13 to 17 are five times more likely to become pregnant than the general population; 60% have given birth by age 24 (82). As a result, parents who were former foster children often have their children removed from them, continuing the cycle (83). Efforts to alleviate these trends emphasize prevention of teen pregnancy in foster care and the support pregnant or parenting youth in foster care by building their parenting skills. These efforts will support parents and reduce child maltreatment and the negative effects removals can have on children, parents, and the child welfare system. Support Youth in Foster Care and Youth Aging out of Foster Care Foster parenting is a heroic, voluntary commitment. Moreover, for children with special needs, Texas already recognizes that foster parents need additional resources. We encourage an evaluation of the adequacy of these supports specifically in the context of youth with behavioral health needs. The same supports should be consistently available to those providing care in the context of kinship fostering arrangements. Peer support by experienced foster caregivers is an important asset that agencies can formalize. Data from 2009 to 2015 shows roughly 4,000 psychiatric admissions for foster care children each year. Moreover, the number of total days foster care children together spend in psychiatric facilities past their initial 8 to 10 days of treatment covered under Medicaid has risen during this time. In June 2009, foster children spent a total of 10 extra days in the facilities but by August 2015 that number had grown to 768 days (84). Despite growing appreciation of the need to support youth transitioning out of formal foster care as they become young adults, their outcomes remain highly problematic. They are at risk for behavioral health and substance use disorders that can escalate to crises needing hospitalization (82).

Low social economical status (poor hygiene) Mode of transmission: Mainly fecal - oral route. Clinical presentation History of direct exposure to a previously jaundiced individual. In the cutaneous form, single or multiple lesions are found on exposed parts, from where Leishmania Donovan bodies can be demonstrated. If parasites persist, treatment may be repeated, two to three times with a ten day interval in between. Since an immediate hypotensive reaction may occur, patients should lie down during the injection and adrenaline should be at hand. Further, due to possible nephrotoxicity, urine must be examined for albumin and/or casts. Treatment Medicine of choice Suramin is the medicine of choice for the early stages of African trypanosomiasis (T. The patient is then rested for 5-7 days and then the above regime of melarsoprol is repeated. This is done once again after a further rest of 5-7 days, thus completing 3 courses of melarsoprol. However, man is infected directly through contact with infected hides or inhalation of spores in the lungs or ingestion of infected meat. The main clinical features are itching, a malignant pustule, pyrexia and rarely pulmonary and gastrointestinal signs.

The common causative organisms of the disease are either staphylococcus or streptococcal bacteria. Clinical features of a breast abscess are tenderness, swelling, red, warm, fever and painful lymph nodes. Instruct the patient to apply hot compresses and a constriction bandage to relieve pain in the affected breast, and to express milk if applicable to reduce engorgement. The main disease forms are bubonic, septicaemic and pneumonic with the former being the commonest. The incubation period is within 7 days and case fatality rate may exceed 50 to 60% in untreated bubonic plague and approaches 100% in untreated pneumonic or septicaemic plague. Treatment When preliminary diagnosis of human plague is made on clinical and epidemiological grounds: Subject the patient to appropriate antimicrobial therapy without waiting for definitive results from the laboratory. Use protective gears (gloves, face mask, and gowns) when managing a suspected plague case. Each febrile episode ends with a sequence of symptoms collectively known as a "crisis. This phase is followed by the "flush phase", characterized by drenching sweats and a rapid decrease in body temperature. Overall, patients who are not treated will experience 1 to 4 episodes of fever before illness resolves. It is transmitted to humans by a bite of soft tick infected by spirochetes known as ornithrodrous moubata. Treatment 361 P a g e Treatment involves antibiotics often tetracycline, doxycline erythromycin and penicillin. The major nutritional disorders in Tanzania, in ranking order, are: Protein-energy malnutrition (deficiency of carbohydrates, fats, protein) Nutritional anaemia (deficiency of nutrients that are essential for the synthesis of red blood cells i. These include: Overweight/obesity Disorders associated with various vitamin deficiencies Disorders associated with deficiency of some trace minerals 1. With regard to manifestation, clinical and anthropometric features are distinguished: 1. Casually the child may appear normal, but on close examination, the child looks thinner and smaller than other children of the same age. He has very severe muscle wasting with flaccid, wrinkled skin and bony prominence. There is failure of growth but the child is not as severely wasted as in marasmus. The child shows hair changes (having turned brown, straight and soft) and rashes on the skin (flaky paint dermatitis). It reflects failure to receive adequate nutrition over a long period of time and is also affected by recurrent and chronic illness. This is a composite indicator which takes into account both chronic and acute malnutrition. Causes include inadequate maternal food intake during pregnancy, short maternal stature and infection such as malaria. Cigarette smoking on the part of the mother also is associated with low birth weight. Most common medical complications in severely malnourished children include generalized oedema, hypothermia, hypoglycaemia, dehydration, anaemia, septicemia/infections and cardiac failure. Treat complications eg dehydration, shock, anemia, infections, hypothermia, hypoglycemia and electrolyte imbalance. Chronic malnutrition (Stunting): nutrition counseling emphasizing on adequate balanced diet and increased frequency of feeding. In this regard men with over 24 percent body fat and women with over 35 percent body fat are considered obese.

Tumour growth In normal tissues that undergo cell renewal, there is a balance between cell proliferation, growth arrest and differentiation, and loss of mature cells by programmed cell death or apoptosis. However, the proliferative rate of tumour cells varies widely between tumours, nonproliferating cells are common, and there is often a high rate of cell death. Tumour growth: Tumour growth can be determined by estimating tumour volume as a function of time. There is a tendency for childhood tumours and adult tumours that are known to be responsive to chemotherapy. Tumours are unlikely to be detected until they grow to about 1 gram, and tumours of this size will contain about one billion (109) cells. Thus, early clinical detection may be expected to reduce but not to prevent the subsequent appearance of metastases. Typical values for the proportion of cells in S phase are in the range of 3 to 15 percent for many types of human solid tumours. Thus, accumulation of cells in tumours is not due simply to an increased rate of cell proliferation as compared to the normal tissue of origin. Most tumours contain nonproliferating cells, and the term growth fraction describes the proportion of cells in the tumour population that is proliferating. The occurrence of extensive necrosis in solid tumours and of apoptotic cells and the ability of tumour cells to metastasize from a primary tumour indicate that there is considerable cell death or loss from many tumours. The rate of cell loss from tumours can be estimated by 76 comparing the rate of cell production (from assessment of the labeling index or fraction of S phase cells by flow cytometry) with the rate of tumour growth. The overall rate of cell production may be characterized by the potential doubling time of the tumour (Tpot), which is the expected doubling time of the tumour in the absence of cell loss. Flow cytometry can be used to estimate cell cycle phase distribution, growth fraction, and kinetic properties of cell populations. Several methods allow proliferating and nonproliferating cells to be distinguished by flow cytometry. The Ki-67 antigen has been used most often as a marker for proliferating cells although its function remains poorly understood. Not surprisingly, wellnourished cells close to blood vessels have a more rapid rate of cell proliferation than poorly nourished cells close to a region of necrosis. Slowly proliferating cells at a distance from functional blood vessels may be resistant to radiation because of hypoxia and to cytotoxic chemotherapeutic drugs because of their low proliferative rate and limited drug access. However, cells in tumours arising in such individuals usually express only one allele of such genes-for example they express only one form (isoenzyme) of the X-linked glucose-6-phosphate dehydrogenase. Other clonal markers include chromosomal rearrangements such as the Philadelphia chromosome in chronic myelogenous leukemia; uniquely rearranged immunoglobulins or T-cell receptors expressed by B-cell lymphomas or multiple myelomas and T-cell lymphomas; and molecular markers whose detection has been facilitated by the availability of gene sequencing. The above techniques have demonstrated clonality in at least 95 percent of the wide range of tumours that have been examined. Renewal tissues such as bone marrow and intestinal mucosa represent a hierarchy of cells produced by cell division and differentiation from a small number of stem or early precursor cells. Recent experiments have suggested that there is a population of cells in some human tumours that express distinct markers on their cell surface and have the properties of stem cells, including self-renewal. Cell proliferation in normal tissues Cell proliferation in a variety of normal tissues has also been studied using thymidine labeling and flow cytometry. Thymidine-labeling studies demonstrated that recognizable precursors of granulocytes and red cells are among the most rapidly proliferating cells in the human body, with a mean duration of S phase (Ts) and mean cell cycle time (Tc) of about 12 and 24 hours. The bone marrow is generally regarded as the most critical tissue for radiation sensitivity following whole body irradiation due to the sensitivity of the stem cells and doses greater than 6-8 Gy are usually lethal without a bone marrow transplant. Intestine: the villi of the small intestine are lined by a single layer of differentiated epithelial cells that do not proliferate, and cell death and shedding of cells into the lumen occurs at the top of the villi. Following whole body exposure to radiation, damage to the intestine can be lethal within a few days if the dose is sufficiently high (>10 Gy for humans) 3. Cell death mechanisms Many types of cells do not show morphological evidence of radiation damage until they attempt to divide. Following doses of less than about 10 Gy, lethally-damaged cells may undergo permanent growth arrest (senescence), interphase death or lysis during radiationinduced apoptosis, or cell lysis as a result of mitotic catastrophe (often after a number of abortive mitotic cycles). A radiation survival curve based on colony-forming ability represents the total cell death within an irradiated cell population as a result of all types of cell death. For the majority of normal and tumour cells, death secondary to mitotic catastrophe accounts for most of the cell kill following irradiation. Why some cells undergo extensive radiation-induced apoptosis within a few hours after irradiation, while others do not, is unclear, but may relate to radiation-induced expression of proteins which trigger an apoptotic response. For example, in hematopoietic cells, radiation can lead to upregulation of pro-apoptotic genes (such as fas, bax, and caspase-3) and/or downregulation of anti-apoptotic genes, (such as bcl-2). The ceramide-mediated apoptotic response to radiation can be inhibited by basic fibroblast growth factor. Senescent or terminalarrested cells are metabolically active but do not proliferate and do not form colonies following irradiation. If a cell does survive and goes on to proliferate after irradiation, delayed chromosomal instability may sometimes be observed in its descendants. One factor that seems to perpetuate the unstable phenotype in irradiated cells is the continued production of reactive oxygen species. Such species or other factors may be released from an irradiated cell and cause damage to neighboring nonirradiated cells. For example, transfer of media from irradiated unstable cell clones to a nonirradiated cell population has been reported to lead to cell death in some of the nonirradiated cells within 24 hours. Similarly the serum from people who have been exposed to whole body irradiation has been reported to be clastogenic for lymphocytes in culture. This bystander effect of radiation has implications for assessment of radiation risk and for health risks associated with radiation exposure as the total cell kill within an irradiated cell population may be greater than that calculated simply on the basis of the number of cells that were directly irradiated. In the assay that is used most often to assess colony formation, cells grown in culture are irradiated either before or after preparation of a suspension of single cells and plated at low density in tissue-culture dishes. Following irradiation, the cells are incubated for a number of days, and those that retain proliferative capacity divide and grow to form discrete colonies of cells. After incubation, the colonies are fixed and stained so that they can be counted easily. If a range of radiation doses is used, then these cell-survival values can be plotted to give a survival curve. The techniques described above have been used to obtain survival curves for a wide range of malignant and normal cell populations. The standard type of radiation was usually taken as 200- or 250-kilovolt (peak) X rays, but now Cobalt 60 -ray energies are used mainly as the standard for comparison.
